A bar pivoted on the right end with a downwards force on the left end rotates in which direction?

When a bar is pivoted at one end and a downward force is applied on the opposite end, the resulting motion is determined by the direction of the force relative to the pivot point. In this scenario, applying a downward force on the left end of the bar creates a moment around the pivot located at the right end.

This moment causes the bar to rotate in the counter-clockwise direction. The force's downward effect, combined with the pivot's position, results in a torque that rotates the bar away from the force, leading to a counter-clockwise motion.

Understanding this principle is essential in mechanics, specifically dealing with torque and lever systems, as it allows for the prediction of movement based on applied forces and pivot points.
